Abstract The management of eucalyptus harvest residues can affect the initial growth and nutrient content of new eucalyptus plantations. We investigated the initial growth and nutritional status of Eucalyptus saligna plantation according to five alternative strategies for management of harvest residues on sandy soil, in the municipality of Barra do Ribeiro, RS. The total height, diameter at breast height (DBH), individual volume and nutrient content in the leaves were evaluated after twelve months. We observed that the maintenance of harvest residues increased growth in height, DBH and individual volume. The levels of calcium in leaves of eucalyptus were higher in the treatments in which harvest residues were removed, whereas the opposite was confirmed for sulfur. The differences found in our study point that the maintenance of harvest residues increase the eucalyptus growth, especially in sandy soils.
